Human beings cannot live without rare birds.
Red-crowned Crane / Picture Source @ Tupe Creative For thousands of years, human beings and birds of all kinds have lived together in the "global village" and established a close partnership with each other. Birds' excellent flying ability, bright colors, pleasant singing voice, wonderful instinctive behavior and the ability of migration and navigation not only arouse people's curiosity, but also give people the enjoyment of beauty and scientific enlightenment.

In order to make atomic bombs and develop the nuclear industry, we cannot do without uranium resources. At that time, the premise for the Soviet Union to assist China's nuclear industry was very clear, and China must have a certain amount of uranium reserves.

Valuable ocean energy of "blue" energy
Ocean energy is a general term for renewable energy contained in the ocean. Including tidal energy, wave energy, tidal current energy (current energy), temperature difference energy and salt difference energy and so on. In a broad sense, ocean energy also includes offshore wind energy and solar energy.

Water is good for all things but not for dispute. | Wang Yanxin
Water is the source of life. From the point of view of geoscience, the water on the earth moves under the action of solar heat energy, earth gravity and molecular energy, and the phase changes occur constantly, from the troposphere of the atmosphere to the depth of the lithosphere, forming a hydrosphere tens of kilometers thick, which has become a basic feature that distinguishes the earth from other planets.

[Earth interview] Academician Li Tingdong: science popularization is the biggest public welfare project.
General Secretary Xi Jinping said that scientific and technological innovation and scientific popularization are the two wings for realizing innovation and development, and scientific popularization should be placed in the same important position as scientific and technological innovation. Without the general improvement of the scientific quality of the whole people, it will be difficult to establish a grand army of high-quality innovation. " Academician Li Tingdong has a lot to say about the importance of science popularization.

Deciphering the black land
The fragrance of rice flowers in black soil There is a saying in the geological industry that "look at the color and recognize the composition". The black soil is black because it contains more dark black humus. Humus can not only provide rich nutrients such as nitrogen, phosphorus and sulfur for plant growth, but also make black soil have a unique structure-aggregate structure. Humus, like glue, binds soil particles into aggregates of several millimeters, which are called small reservoirs and small fertilizer reservoirs of plant roots, which are unmatched by clay, sand and other properties. Therefore, the black soil has high fertility and good character, which is worthy of the reputation of the king of the soil.

China is rich in volcanic geological relics, and 25 national geoparks with volcanoes as the theme have been built. Each Geopark has its own unique volcanic landscape, which not only has a high ornamental value, provides us with a good place for leisure and entertainment, but also can better protect the geological relic landscape and ecological environment. More importantly, they are important witnesses to the evolution of the earth's history, a window through which we can spy on the earth's movement, and a natural place for popular science education in geology.
Under the influence of the neotectonic movement, five submarine volcanic activities occurred in the coastal-shallow sea environment around Weizhou Island. 1.42 million years ago, Weizhou Island played the symphony of Weizhou Island volcanic eruption. at that time, the eruption took place in the crater of Henglushan volcano, and the basaltic lava overflowed from the volcanic cone to flow around, forming a shield-shaped volcanic topography with high and low surrounding areas in the center of Weizhou Island. At present, the basalts formed in this period are mainly hidden below sea level, but some basalts can be seen along the intertidal zone when the tide goes out in the western corner and Houbeitang in the north of Weizhou Island. they are the founders of Weizhou Island. 36000 years ago, volcanic activity was dominated by exhalation magma eruption, which formed typical low-level crater and thick basement wave accumulation, experienced weathering and marine erosion, and shaped the geomorphological landscape of Weizhou Island today.

Travertine Pool in Hengduan Mountain-- A masterpiece of hydrosphere material cycle
Jiuzhaigou-Shuzheng Qunhai Cahuabian stone dam color pool is one of the main forms of travertine deposition. When the local surface water flows on a gentle slope, it is blocked by dead branches and leaves, and the flow velocity changes abruptly, which leads to the poor deposition rate of calcium carbonate and the formation of calcium flake stone dam color pool landscape. Cahuabian stone dam color ponds often appear in groups, with layers and beautiful lines, which is a fantastic scene of water color.
